PRODUCTION DATA
This diagnostic mechanism allows the controller to check if the sensitivity of the Hall sensor is within the factory-determined limits by checking the resistance of the Hall-effect sensor. In this check, the biasing and multiplexing control of all directions of the Hall sensor (X, Y and Z) are also checked.
To run this check, the controller must enable the check and set the scheduling for the run. During this check, the Hall sensor is not available for magnetic field conversion. The user can configure the ALERT pin to toggle if an error is detected. This error is also reported in the user register.
Run Mode | Every time a magnetic measurement is initiated and completed |
Configuration Register(s) | DIAG_EN to enable test. DIAG_SEL to schedule when the test is run |
Fault Register Bit | ZHS_STAT, YHS_STAT and XHS_STAT |
Impact if disabled | If disabled, any failures or drift in the Hall-effect sensor properties and biasing will not be detected, leading to potentially incorrect magnetic field conversion |
